Electronic digital products are updated faster than wallets. Therefore, many people still use non-smart phones (I am one of them), but players who love to play mobile phones know that smart phones can bring a lot of fresh and fun things, and people have the best experience. For example, Tencent (qq)'s latest WeChat can send texts, emoticons, pictures, and voice and video.
But if I am still using a non-intelligent machine like this, I will only complain. At the same time, many small basin friends will ask:
Can I install WeChat on my computer? How to install WeChat client on my computer? How to use computer to play WeChat? The answer is yes. As for whether you believe it or not, it is up to you, anyway, I believe it!

So what is Android? Android is an operating system based on the Linux open kernel. It is a mobile operating system announced by Google on November 5, 2007.
Android was developed by the company formerly known as "Android", and after Google acquired "Android.Inc" in 2005, it continued to develop and operate the Android system, which uses a software stack. The architecture of the software stack is mainly divided into three parts. The underlying Linux kernel only provides basic functionality, and other applications are developed by companies themselves, some of which are written in Java.
Solution: Computer simulation of smart phones, saving traffic, and convenient! Install an Android system through the computer (because Android is open source). All nonsense in front, mistakenly entered the topic first!
